The Army on Friday identified three Fort Carson soldiers who died Tuesday when a roadside bomb exploded near their Humvee. Killed were Staff Sgt. Ryan E. Haupt, 24, of Phoenix, Ariz.; Sgt. Norman R. Taylor III, 21, of Blythe, Calif., and Pfc. Nathan J. Frigo, 23, of Kokomo, Ind. The three, all assigned as snipers in the 3rd Heavy Brigade Combat Team, were riding together to protect a convoy traveling between Baqouba and Balad, Iraq, when the bomb went off. The deaths came days before the brigade was scheduled to begin coming home from Iraq. The first soldiers to return to Fort Carson after the brigade’s year-long tour are due back Sunday. The deaths bring Fort Carson’s toll to 173 soldiers killed since the Iraq war began in 2003, including 23 from 3rd Brigade. Bombs have been the biggest killer of Fort Carson soldiers in Iraq, claiming 66 lives.
